high BIT RATES - Don't believe it !

For most of the time this may be true.

But it is also possible for a really bad quality recodring to be recompressed into higher bit rates to give an impression of superiority. But you can't improve sound quailty if it wasn't already there. Not unless you use an audio editing programme

For instance, if a track is lifted from vinyl with hiss and cracks included and originally compressed at 128, recompressing at 192 doesn't change anything, it only makes the file larger.

Just a thought for those people who are sometimes disappointed with bad quality high bit music files

Hi Antonym,

You will find quite a few posts on this topic by some of the very tech savvy members, including Red Smurf and Gluteous Maximus.

One question though, what audio editing programme allows you to "improve" sound quality that is not already there? How would you define "improve" in this context?

Cheers,

Squash

PS Is that your eye?

But it is also possible for really bad recodrings to be later recompressed into higher bit rates to give the impression of superior sound quality. You can't improve sound quailty just by recompressing if it wasn't already there.

For instance, if a track is badly ripped from vinyl with it's hiss and cracks and compressed at 128, recompressing at 192 doesn't change anything, it only makes the file larger.

Hi antonym2m2.


Just like Squash says, we have some really encoding savvy people here

Look up forum member Red Smurf and read some of his posts. Like these two for instance: http://www.aom3.org/forum/25539-post18.html and http://www.aom3.org/forum/4560-post13.html

And you could also take a peek in these two threads:

Hey Antonym, I notice you have edited your post (without giving a reason for doing so) to remove the remark about sound editing programmes I asked a question about in the subsequent post.

When you do that it makes part of my post incomprehesible to other members who have not read your un-edited version.

I don't mind if you would prefer not to reply to my question, but that is not the way we generally do things around here

Regards,

Squash

Hi squash54

I guess depopping software for cleaning up vinyl and tape rips could fit the spec Audacity and WavePad Sound Editor from NCH (both free) have noise and click filters.

Hi GM,

I got the impression Antnomym was referring to something more sophistocated than WavePad type ripping programmes.

I have been slowly ripping a vinyl collection and have tried a number of these, including WavePad. I have not noticed much difference in the results as far as the uncompressed files are concerned. Also, I have got to the stage where I mostly don't convert to mp3 because memory has become so cheap and a large NAS is very convenient and useful in so many ways. I now just remove any loud pops and don't worry about the rest. As someone remarked in another thread on this topic "It sounds so retro, man."

Hi squash54

I guess you get what you pay for

There are claims that upsampling using a digital signal processor makes music 'sound' better, in the same way that interpolation can be used to increase the apparent resolution of a photograph by calculating new dots in between the existing ones. Have a look at http://www.anagramtech.com/technology/q5-upsampling/ . Obviously you can't put back lost information, but maybe you can make it 'sound' better. I can't find a definitive answer to this on the web. Anybody know a top-flight professional sound engineer with perfect hearing, a laboratory and lots of spare time?

Hi GM, thanks for the link.

I found a Cambridge CD player using Anagram's Q5 upsampling technology as well as a "plain english" explanation (obviously written by Anagram) of what it does and the benefits it delivers for the listener.

Cambridge Audio 840C CD Player - CD Players - CAMB840C

I expect with a bit more searching I should be able to turn up a subjective A/B comparison test of CD players with and without this technology.

Actually, I have sort of lost interest in this end of the hi-fi audio scene (I mean the CD player/pre-amp/power amp end) in favour of the loudspeaker and frequency cross-over end. I have a reasonable player (it does DVD-A and SACD and just about everything else), AV processor and multiple power amps with lots of 'head-room'. However, my experience has been you get a bigger bang for your buck with "improvements" at the loudspeaker end of the sound reproduction process and it's something I can DIY, to a large extent.

I have noticed that the price of these 'top end' players seems to be coming down significantly so I might make a visit to a few of the better audio retailers in the near future and have a listen to a few.

Regards,

Squash

I'm entitled to edit my post if i want too...that's why the facility's there isn't it ?

furthermore, i can't be expected to immediately respond to your particular question just because you expect it there and then. Some of us don't sit around all day waiting for people to comment

What sort of a forum participant are you, demanding explanations and responses that suit you.

"That's not how we do thing round here"...Blimey !!.

If you expect people to answer your comments immediately perhaps you should obtain their private mobile numbers first.

I would have loved to explain about audio editing programs but you need to be less hostile and more patient

Hmm! I think I will just let a forum moderator apply their wisdom to what is appropriate editing where the effect may be to distort subsequent posts.

Cue, Nightfly or Solaris.

Gary Numan!!

In the April 29, 2001, edition of The Sunday Times Gary Numan stated:

"Polite conversation has never been one of my strong points. Just recently I actually found out that I'd got a mild form of Asperger's Syndrome which basically means I have trouble interacting with people. For years, I couldn't understand why people thought I was arrogant, but now it all makes a bit more sense." (Source:Wikipedia)

Sure does
